IS200TBCIH1BCE Contact terminal board GE
The IS200TBCIH1BCE developed by General Electric was manufactured to be a part of the Mark VI series for gas and steam turbine management.
This board is a very long circuit board containing a number of electronic components including two terminal blocks that are designed to hold a collection of terminals. These terminal blocks contain forty-eight silver metal terminals, or twenty-four terminals each. They are identified by a number written in white writing and labeled TB1 and TB2. This board also features five solid red capacitors positioned between the terminal blocks that are small and completely round. Additional components populate the middle of the board and have been arranged into many parallel rows of four components each.
It is designed with filters that reduce high-frequency noise and also suppress surge on each input. A pair of terminal points is used for each input, with one screw providing the positive dc source and the second point providing the return to the board. Current loading is 2.5 mA per point for the first 21 inputs while the last three have a 10 mA load. The board has no hardware settings or jumpers.
